PERCY DAVID HEDDERWIGK, OF GLASGOW, NORTH BRITAIN, ASSIGNOR BY MESNE ASSIGNMENT, TO R. HOE & (30., OF NEW YORK, N. Y.

PRINTING- SPEGIFICATION' forming part of Letters Application filed August 16, 1875.

To all whom it may concern:

Be it known that I, PERCY DAVID HEDDER- WICK, of Glasgow, county of Lanark, Scotland, have invented certain Improvements in Web-Printing Machines, of which the following is a specification.

In the accompanyingdrawings, in which like letters indicate like parts, Figure 1 represents a longitudinal sectional elevation of'a printingmachine provided with mechanisms for perfecting and delivering one or two webs. Fig. 2 represents a longitudinal sectional elevation of a detached portion of said machine, showing a delivery mechanism consisting of two I 5 folding-drums, one of which is in section. Fig. 3 is a part plan view of Fig. 1. Fig. 4 is a diagram illustrating a mechanism for stopping the machine when the web is broken, and Fig. 5 is a detached longitudinal sectional elevation of oneof the delivery-drums.

The invention consists ofa printing-machine provided with mechanism for perfecting one or two webs of paper, severing the same into sheets, and delivering and piling the sheets;

also, in a rotary folding mechanism co-operating with a perfecting printingpress, and in certain details, all of which will bemore specifically hereinafter pointed out.

The mechanisms are supported in an open frame-work, A. The two webs of paper 0 O to be printed are respectively wound upon two rollers, B and B, supported in brackets or bearings. (Not shown.) Upon the upper part of theframe-work A two type or stereotype cylinders, D and D,'and four impression-cylinders, E E and F F, are mounted and arranged in such a manner that two of the impressioncylindersnamely, those marked F.Fare adjacent to each other and situated between the 4' type-cylinders D and D, while the two remaining impression-cy1iuders, E E, are, in consequence, situated respectively at the outer side of the said type-cylinders D and 1). Each of the cylinders D and D is provided with two inking apparatuses of the usual roller type. The ink, being placed in the reservoirs I I I I, is conducted to the type-cylinders by means of the ordinary train of iuk-distribu ting rollers 2, acting with their peripheries in contact, the

lowest roller of the train on the under side and MACHINE.

Patent No. 231,316, dated August 1'7, 1880.

Patented in England May 31, 1870.

the extreme roller of the train on the upper sidebeing partially immersed in the ink, while the latter two rollers of the trains farthest from the ink-reservoir are in contact with the typecylinders and distribute the ink thereon. 5

The object of supplying inking apparatuses at both the upper and lower sides is to give a separate inking for each printing operation upon the two webs.

To facilitate the operation of taking out or putting in types, stereotype-plates, or the type or stereotype cylinders themselves, the inking apparatus on the upper side is movable, (by preference in a circular arc,) so that it may be drawn away from interfering with any of the above-mentioned operations, as indicated by dotted lines in Fig. 1.

The delivering mechanism is as follows: Two revolving drums, G and G, are mounted at suitable points in the frame, and each consists, as shown in Fig. 5, of end plates or frames, a, between which is fixed the drum proper, which consists of a thin plate, I), bent cylindrically, and at intervals either perforated or slotted with openings, as shown in Fig. l. The end 7 frames or plates, a, of the drums G G are each centered and free to revolve upon hollow tubular bearings 0 which are secured to the framework A by means of screwed studs or bolts (1 being passed through flanges e formed upon the hollow bearings 0 To the outer ends of the said cylindrical bearings c a pipe, f, is attached, which is in communication with an adjacent fan, pump, or other apparatus, whereby a blast orstron gcnrrent of airis passed through 8 5 the pipe fand the hollow bearingcfl thence into a pipe, 1., which is situated concentrically with and extends from the bearing 0 across the e11- tire length of the drum G or G. The said pipe t is provided at suitable intervals with blow- 9o pipes a as shown in Fig. 1. The revolving drums G and G are each provided with two distinct sets of gripers, as shown at a a (see Fig. 2,) which gripe the web at its edges, and which operate as hereinafter set forth.

Situated adjacent to the drums G and G, respectively, with their peripheries in contact therewith, are two cutting-rollers, H and H, each of which has at a certain part of its periphery a knife or sharp cutting-instrument, I00

which is brought into contact with the peripheries of the drums G or G at regular intervals, as the rollers Hand II are revolved by means of aspur-pinion, p, fixed upon the axis of each and geared into corresponding spur-wheclsp, fixed upon the axis of the drums G and G, respectively. The functions and operation of these blades are hereinafter more specifically set forth.

The arrangement of gearing by preference employed for the transmission of motion to the working parts of the whole apparatus is particularly shown in Fig. 3.

The shafts a or. upon which the typecylinders D and D are fixed, have each bevel-wheels b I)" fixed upon one end. The said wheels I) I) are geared into corresponding wheels 0 0', respectively, which are fixed upon a shaft, X, carried in bearings .r, supported on brackets 00 formed upon one of the side frames, A. Upon one end of the shaft X fast and loose pulleys y and 3 are situated, provided for the purpose of transmitting a rotary motion to the said shaft X and the type or stereotype cylinder D and D through the intervention of a driving band or belt which is in communication with some adjacent motor. In order that the impression-cylinders may in like manner he made to revolve or kept stationary, as may be desired, the shafts a a of the type-cylinders D and D have upon their ends opposite to those upon which the bevel-wheels I) b are situated spur-wheels d d fixed. Each of these is in turn geared respectively into two correspondingwheels, r c or e e, situated upon their adjacent shaftsff f fthat is to say, the wheel 01 is geared into the wheels 1" 0 causing the impressioncylinders E and F to revolve, while the wheel (I is geared into the wheels 6 c in like manner. causing the impression-cylinders E and F to revolve; and in order that any of the impressioncylinders E E or F F may be kept stationary while the type-cylinders D I) are in motion, it is provided that any of the wheels c 1' c a may be drawn out of contact with their respective driving-wheels d (1 the shafts f f f f be. ing elongated for this purpose.

In order that the motion of all the moving parts of the machine may be stopped when a web breaks mechanism is provided, as shown and as particularly illustrated by Fig. 4.

Above and freely rolling on each of the impression-cylinders E E F F are rollers I), which are attached to the extremities of bellcrank levers c, centered upon studs (1. The rollers I) lie upon the top of the web as it extends over the upper side of the impressioncyliuders, and if the web breaks one, any, or all of the rollers 0 drop into the slots a", (which are those made for fastening the impression-cylinder blankets in the usual wellknown mauner,butwhich may beindependent slots provided for this express purpose,) and which has the effect of drawing down the ends of the bell-crank levers c, to which the rollers b are attached, while their opposite ends 0 are in consequence forced outward in the direction indicated by the arrows, and as these opposite ends are in contact with the tappets 0, which are fixed upon a rod, f the rod is thereby moved in the direction indicated by the arrow. To the end of the rod f a bellcrank lever, g, is jointed, the fulcrum of which is centered upon a stud, It.

When the rod is moved in the manner at ready described it drags with it the end of the bell-crank lever g, to which it is jointed, while the opposite end of the said bell-crank leverg is moved upward and thrown out of contact with the tappet i, which is fixed upon the shaft k. Upon this shaft k the belt-guide L is also situated, against which the end of a strong spring, m, (or its equivalent as a weighted lever) is brought to bear. Immediately that the tappet z' is relieved from contact with thelower end of the bell-crauk lever gthe pressure from the spring 11: instantly draws along the beltguide L and the shaft is a sufficient distance to shift the belt from the fast pulley y to the loose pulley and thereby stops the motion of the working parts of the machine.

Having now described the construction and general arrangement of the chief parts of my improved printing apparatus as in one arrangement, I will now proceed to set forth its operation.

The end of one of the webs of paper (J which is wound upon the roller B is drawn upward and passed over the outer impression-cylinder, E; thence it is passed downward,and, being subjected to contact with the type or stere0- type cylinder ]),is thereby printed upon one side. In being passed onward it is next led over a carrying-roll, 1, thence downward to another and corresponding carrying-roller, I, whence it is led along the under side of the apparatus, being supported and conducted in its course by traveling bands or tapes extending between the stretching-rollers u a a when, having arrived at the latter, it is brought into contact with and conducted round another carrying-roller, I, thence upward, when it is passed over another carrying-roller, I, from which it is conducted and passed over the impression-cylinder E, in passing around which it has that side which has not been printed upon brought into contact with the type or stereotype cylinder D, and is in like manner printed. From the impression-cylinder it is then passed over the revolving drum G, and is caught upon its edges by one set of the gripers a or a with which the said drum is provided, as by the gripers a, as seen in Fig. 2, which seize hold of the edges at one end of the printed web, and carrying the web around with them, the said drum also revolving the cuttiug-cyliiuler H until the knife or cutting instrument, situated at its periphery, is, in passing through a revolution, brought into contact with the web upon the periphery of the drum G, when it severs or cuts the said paper into sheets of the requisite length. The detached portions of paper when cut ofl' arein the lengths corresponding to the circumferences of type on the cylinders D and D. Immediately before the cutting of the web has been accomplished the second set of gripers, as a situated upon the drum at a point opposite to the set of gripers (5*, just referred to, has caught hold of the web close to and behind that part where the out has to be made, the web thereby being secured from being thrown or falling off from the drum G while passing through the lower half of its revolution, and until arriving at the point where the gripers are released and the sheet freed to be removed from the drum G. It is blown off from the drum G by means of a current of air passing from the blow-pipe a and impinging on the inner side of the paper by issuing through the perforations, so that it is finally deposited upon the receiving-board J, provided for the purpose. The said current of air is intermittent, and it is adjusted by the opening and closing of a valve so as to come into action at the desired instant.

The direction in which the web is drawn and conducted from one part of the series of operations to the others is indicated by the arrows upon Fig. 1.

With reference to the end of the second web or roll of paper-that one marked 0, which is wound upon the roller Bit is drawn upward and passed round the imprcssion-cylinder F, by which it is printed on one side through being in contact with the adjacenttype orstereotype cylinder D. It is then conducted round and passed downward between the impressioncylinders F and F, and it is then conducted round the latter and drawn upward between it and the second type or stereotype cylinder, D, whereby it is printed upon the opposite side through being in contact with the said type or stereotype cylinder D. The web is then drawn onward and passed round a carrying-roller, H thence it is drawn upward and passed over another carrying-roller, K, from which it is conducted to the revolving drum G, whence it is cut and treated in a manner in every respect similar to that hereiubefore described with reference to the first web. and the detached sheets are finally dcposited upon the receiving-board L. The (1ireetion in which the second web is drawn and conducted is clearly shown by arrows upon Fig. 1.

When it is desired to fold the sheets instead of piling them flat, the apparatus illustrated by Fig. 2 is substituted at the delivery end of the machine, the drums G and G being provided with different mechanisms than those forming the blast-delivery simply.

The webs of paper, after having been subjected to the double printing operations, are led to the revolving delivery-drums G and G, and when they are brought onto the surface thereof the opposite edges of each web are seized by gripers a or (P, which open laterally, and are of any suitable kind, the position of which two sets of gripers upon the drums G G is shown in Fig. 2 by one member of each set, it being explained that while the position of the drum G is indicated by a line, it is fitted with gripers and other moving parts similar to those shown in connection with the drum G. Each web is then drawn onward and partially wound round each of the drums G and G until, having been carried thereby through a portion of the revolution of the drums G and G, each web is severed or cut by the action of serrated knives I)", which are, at suitableintervals of their revolutions, pressed toward the periphery of the drums G and G, in which openings or grooves are formed, and into which the cutting-edge of the knife 11 advances.

Each knife I), when being pushed forward, is actuated by means of a tappet, c", which is fixed upon a disk, d, the said disk (1 being upon a shaft, 0, and made to revolve therewith at such a velocity as to bring the tappet 0" into contact with and push a light frame, f, to which the knife U is attached, toward the drum G or G at intervals corresponding to the length of the sheet required and in proportion to the circumference of the typecylinder. In'imediately that the web has been cut in the manner now described the frame f is pushed backward or away from the drum by a spring (not shown in the drawings) toits forlner position, and while in the act. of being so pushed back the cutting-edge of the knife is brought into contact with a brush or its equivalent situated in such a position as to insure the said contact. By this means any small portions of paper or detached fiber or dirt that may have adhered to the said outting-edge of the knife b during the cutting operation are removed, and the knife is thus kept clean for the succeeding cut. Simultaneously with the cutting of the web in the manne1"hereinbetbre described the web is again caught (close behind where it was severed) by another set of gripers, (0 similar to those at already referred to, but placed apart therefrom at a distance equal to thelength of sheet required, while during the next succeeding instant of time the first set of gripersnamely, those marked a, but which by the continuous revolving of the drum G are now situated at the point where the gripers a are shown in Fig. 2-are released,and the center of the detached sheet is pushed inward between folding-rollers 3 4 by means of a folding-blade, 9", (whose frame and gearing are in every respect similar to the frame and gearing of the knife b,) and brought into contact with traveling tapes 5 6, by which the sheet is driven inward in the direction indicated by the arrows, and carried round roller h", whence it is conducted outward in the direction of the periphery of the drum, when its leading end-that is to say, the middle or fold of the sheethaving arrived at the rollers 7 S, (which, through the continuous revolving of the drum G, are then situated at the IOO point 9 it is fed out from the tapes 3 4 and emerges from the rollers 7 8 in the drum G at the same speed as, but in an opposite. direction to, that in which the periphery of the drum G is traveling. Vtheu the rollers 7 8 have arrived at the point g" the sheet is entirely released from the tapes and cleared from the rollers 7 S, and will be in the act of falling onto the board J, in which act it will be assisted by a blast of air from within the drum. The blast of air is caused (as hereiubefore described) by a fan-pump in connection with the fixed pipe 1, on which the drums (l and (i revolve.

In the under side of the pipe 1 is a slit, t. As the blow-pipes a, which revolve with the drums, come alternately opposite this slit t, a current of air rushes through the slit it into the blow-pipes n and out through the perforations or slots in that part 10 of the outer casing of the drums G and G which covers the mouths of the blow-pipes n at the moment when the sheets are freed from the tapes inside the drums G and (I. If, however,the weight of the paper used be snliicieut to cause the sheets to fall without any assistance the blast of air may be dispensed with.

The roller It" is made to revolve by means of any suitable arrangementof gearingcommunieating with any of the revolving shafts in the mechanism, the proportions of the said gear ing being such as to cause the periphery of the roller M to travel at the same velocity as the periphery of the drum G. By this mechanism and connecting-gearing or surface contact all the tapes are caused to travel at the same velocity, and the distance over which they conduct the sheet is in correspondence with the time which the rollers 3 4 have occupied in traveling from their position of cooperation with the folding-blade g" around to the position indicated at or from that indicated by g to that of 9 By this means each sheetis in succession accurately folded and dclivered in the same position.

It is to be observed that the arrangement of the series of type and impression cylinders with their axes placed in a horizontal plane may be varied. Thus, they may be arranged vertically or at any angle of inclination; or, in place of arranging the impression-cylinders in a horizontal line with the type-cylinders, the impressioncylinders may be placed above or below the type-cylinders. Moreover, the delivery attachment, as well as the foldingdrum, may be attached to a press arranged to perfect one web only.

Having now described the nature and operation of my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of a rotating foldingblade automatically proiected in the act of doubling a sheet carried upon a supportingdrum into a recess therein with said drum and suitable mechanism with which it is provided for receiving and holding said doubled sheet, substantially as shown and described.

2. In combination with a rotating foldingblade, a rotating drum carrying folding-rollers, having a series of tapes leading therefrom, whereby a sheet is folded into and delivered from the drum while it is revolving, substantially as shown and described.

3. A rotating drum provided with a pair of rollers, through which the sheet is folded, and conducting-tapes which carry and deliver the folded sheet during the continuous rotation of the drum, substantially as shown and described.
